Email notifications not triggering in F5 LTM
Hi Experts
We upgraded Big IP 1600 LTM version 10.X to version 11.2.1 recently . I had configured email notifications earlier in LTM (such as to trigger Alerts via Email if Node or Pool member down ) which use to trigger successfully ; however email notifications are not triggering anymore. I have observed 2 things
a) The SMTP configuration (From , To , Subject) in "alert.conf" file disappeared after upgrading to 11.2.1 .
b) In the 10.X version "postfix" service use to be there which is now replaced by "ssmtp" .I configured the parameter "mailhub=mail.your.domain" in the "ssmtp.conf" file ; however i am getting following error while sending Test message
send-mail: Cannot open mail:25
Note : I have checked that i can telnet successfully to the SMTP Relay server on port 25
Kindly assist on it
Thanks , Ankur
